.The inventionrelates to a machine for making brushes of the typewherein a quantity of doubled or folded fibers is held.by. a metallicferrule. Brushes, of this type are commonly provided in connection witherasers for typewriter use.

Thelgeneralobiect of the invention i .to providexa;machine forautomatically feeding and moving a succession of ferrules, for insertingfolded fibers in the successive ferrules; for squeezing the-successiveferrules to hold or look the fibers. implace, and for trimming to therequired length the fibers held'by the successive ferrules.

While the complete machine includes means for feeding ferrules and,means; for trimmingthe fibersrit will be understood that the inventionis not necessarily limited to a machine having thesefunctions, as theferrule feeding couldbe effected manually andv as the fiber trimmingcould be done by a separate machine. 7 j V Further-and more specificobjects of the inventicn are to provide various featuresof mechanism andarrangement for attaining the stated general object of the invention.

I-nthe drawings we have shown in detail a preferred embodiment of theinvention, but it will be understood that various changes may be madefrom the construction shown, and that the drawings are not to beconstrued as defining or limiting the scope of the invention, the claimsforming a part of this specification being relied upon for'that purpose.

Fig. 1 shows a brush of the. typewhich a machineembodying the inventionis adapted to produce. The brush includes a metallic ferrule A'. whichis closed at its lower end and open at, its upper end. The ferrule A ispreferably substan--- tially rectangular in transverse section. vFibersB are carried by the ferrule, and the several fibers are looped orfolded with the looped or folded portions thereof inserted into theferrule to form a tuft. After the fibers are in place, the ferrule issqueezed or indented at least'at one side, 'asindicated' at C, so as tolock the fibers in place. After'the fibers'have beeninserte'dfland.locked in place, j-the upper ends thereof", are trimmed so as to provideuniformity of length.

The machine as shown in Figs. 2 to 22fc'omp'rises' a ferrule movingmeans which is preferably a I ferrule supporting mechanism having aplurality of uniformly spaced'ferr'ule receiving recesses," the i saidmechanism being adapted to be moved inter mittently in one directionlsoas tolbringrthe' shaft of a motor 34 on the main frame l8.

3 ferrule holding recesses to successive stations at which variousoperations take place. At one station ferrules A are fed into therecesses in vertical jpositions, and at another station fibers B arefolded and inserted into the ferrules in the recesses. Following theinsertion'of the'fibers, the

ferrules are squeezed or indentedto lock the At a third station thefibers Terms such as said fibers in place. are trimmed to uniformlengths.

Whorizontal and "vertical are herein used to more conveniently set forthrelative positions or arrangements. Such terms are: not. tobei' conr.

and this locks the index plate against rotation.

The directions of rotation of the several parts are such that the crank12 moves in the counterclockwise direction. As it so moves, the roller1'4 strued as in any way limiting the scope of the in-- vention.

Driving and indexing mechanisms Referring more particularlylto Figs; 1'to 6,. It.

represents a base which carries the major portion of the operating partsof the machine. The base" is shown as being generally rectangular, andit is supported on a'framework [8 which may have any suitable orconvenient form. The before-mentioned ferrule supporting mechanismpreferably comprises an endless series of ferrule supporting units 20.While the invention is not necessarily so limited, the several units arepreferably secured to an endless chain 22. The chain 22 extends aroundand is supported by idler sprockets;

24' and 26 which are supported on transverse shaftsrotatable in bearingssecured to the base it. The ferrule supporting units 20 will be hereineafter described in greater detail and it is sufficient for presentpurposes to say that each of them has a recess'which is open at the topwhen the unit is in upright position. Each recess is of such size as topermit a ferrule to be readily fed into it, the i open end of theferrule being exposed at the top.

At the rear of the machine is a belt pulley 28 which" is'carried by ashort transverse main drive shaft. Thepulley 28 is driven by means ofbelts 30 which extend around a pulley 32 carried by the Secured to themain drive shaft is a pinion 35 which meshes with a gear 38- secured'toa short jack shaft 40. The jack shaft is mounted in bearings carriedbybrackets 42 and 44. Also secured to the jackshaft 4'!) is apinion 46which meshes with a gear 4'8 secured to a sleeve 50, this sleeve beingrotatably mounted on the main drive shaft. It wli be seen that by meansof the gearing described, the. sleeve 50is rotated at a speedconsiderably less than that'of'the belt pulley 28 and of the main driveshaft. 7 The gear. 48meshes with a gear 52 secured to a transverse shaft54' which is shown most clearly in Fig. 6. The gears'48 and 52 are ofthe same size and therefore rotate at the same speeds, but in oppositedirections. The shaft 54 is rotatable within a transverse sleeve 56,which is rotatable independently of the shaft. v The sleeve 56 issupported at the rear in a bearing 58 carried by the before mentionedbracket 44' and is supported at the front in a bearing at Win a bracket62 adjacent the front of the machine.

Secured to the sleeve 56 is a gear 64 which car ries an indexing plate66 constituting-part of an indexing mechanism of the Geneva motion type.As shown in Fig. 2, the plate 66 is provided on its rear face with aplurality of radial grooves 68, 68,

sixsuch groovesbeing shown. The plate 66 is provided at its peripheryand-between the respective grooves 68, 68 with partly cylindricalrecesses, 10; 10. Secured to the front end of the sleeve 56 is a crankI2 which is shown in detail in Fig; '5. The crank carries at" thefrontside thereon enters-the next adjacent radial groove 68 and at thesame time the projection 16 moves out of the corresponding recess 10.Engagement of the roller 14in the groove 68 causes the index platejandth'eparts directly connected thereto to move in the clockwise direction.The index plate ismoved through an angle corresponding to the anglebetween successive radial grooves, that is, through 60". As theroller'lt emerges from-the groove-'68,- the projection E6 on the crankenters the -next following recess T0 and again locks the index plateagainst rotation. The crank lZ rotates continuously and serves duringeach rota-" tion-to index the plate 66 and the gear 64 in the clockwisedirection through successive angles; of:

The gear 64 meshes with a gear 18 which'is' The gear '18 ismost clearlyshown "in Fig 6. secured to a transverse-shaft which isrotatable inbearings 82 and BMsecured to' the underside of -tlie base 15'. Carriedby the shaft 89 is a: srirocket wheel" 86' which meshes withtheunderside oftheupperruncr' the before-mentioned It -will:be' seen that:by means endlesschain 22-; of the'indexing mechanism and the other partsthat have been-described, the chain 22- and the ferrule supportingunits- 20; 20 carriedtherebyare moved intermittently. The construction 1issuch that eachintermittentmovement is equal to the distance betweenthe ferrule-receiving recessesim each intermittent movement of the chainand ofv the units carried thereby.

Fiber inserting mechanism Ferrules A are fed into the recesses of thesev-.

eral units 20, 20 as they pass aferrule receiving station near the rightend: of the machine, such feeding being preferably effected by means ofmechanism to be hereinafter fully described; By reason of theintermittent movementsthat have been described, the units 20, 20 aresuccessively moved to a station near the center of the machine at whichfibers are inserted therein. This fiber inserting station isverticallybeneath the axis of the before-mentioned transverse shaft 54.

Connected to thesleeve56 which is intermittently rotated by the indexingmechanism is'a hub 88' to which is secured 'a-fiber carrying disc 96which is shown most clearly in Figs. 6 and '7. The axis'of-the disc 90is-horizontal and it preferably extendsas shown transversely of thedirection of movement-ofthe ferrule carrying The disc Bilhas'therein atits periphery a plurality of'fiber receiving notches 92, 92, and whenthe sleeve-Wand the disc 90 are indexed through 60 as has been describedthere are six notches. The notches are so positioned that at the end ofeach indexing movement one of them is at a transfer positionatthe'bottom and is vertically above and opposite the open end of aferrule A carried by the corresponding ferrule supporting unit 20.

Positioned vertically above the disc 90 is a fiber magazine indicatedgenerally at 94. The details of the magazine 94 do not constitute anypart of the present invention and it is sufficient to say that themagazine serves to maintain a mass of horizontally and preferablytransversely arranged fibers B in a position above and in contact with aportion of the upper periphery of the wheel. As each successive notch 92passes the mass of fibers B, a quantity of fibers sufficient for onebrush enters the notch and by reason of the successive indexingmovements is carried to the before-mentioned position at the bottom ofthe disc. At the last-mentioned position the fibers are horizontal andthey extend across the upper open end of the corresponding ferrule atthe fiber inserting station. I

In order that the fibers B may be retained in the successive notches 92,92, there is provided a guard 96 which is shaped to closely fit the discat one side thereof. Preferably, the guard 96 is grooved so that theperipheral portion of the disc 90 is entered in the groove. In order toinsure the entry of uniform quantities of fibers into the notches, theguard 96 preferablyoarries a separating member 98 which is shown in Fig.7 and which is also shown in section in Fig. 8. The member 98 has anarrow edge which is inclined outward and in the direction of discmovement as shown in Fig. 7. The inner edge of the said member issubstantially at the periphery of the disc 90. When the disc is indexed,the corresponding notch 92 passes beneath the lower edge of the member98 and any fibers in excess of the required quantity are restrained frommovement with the disc. The guard 96 has an inclined guiding surface atI00 which engages the fibers in the notch and forces them inward andcompacts them to a limited extent.

Referring particularly to Figs. 9, and 11, it will be seen that aportion I02 of the lower end of the guard 96 extends toward the leftbeyond the position of the lowermost notch 92. The extended portion I02of the guard does not exactly follow the curvature of the periphery ofthe disc- 90, but is inclined relatively inward so that the fibers inthe lowermost notch are bent upward to a slight extent. The portion I02of the guard has a slot I04 therein adapted for the passage of thefibers and of a vertically movable fiber inserting tool to be nowdescribed.

A slide I06 is provided which is vertically reciprocable in suitableguideways provided in'the bracket 62. Secured. to the shaft 54 androtatable therewith is a cam drum I08 having a cam groove I I0 in theinner or rear face thereof. The slide I06 is provided with a studcarrying a roller II2 which is positioned within the cam groove IIO. Aswill be apparent from an inspection of Fig. '7, the cam groove I I0 isso shaped that it serves to reciprocate the slide I06, the slide beingmoved to its lowermost position immediately the slide I06 that it isimmediately adjacent the disc 90.

Fig. 9 shows the tool H4 in the upper position which it occupies duringeachintermittent movement of the carrying units 20. Immediatelyfollowing each intermittent movement of the units the tool is moveddownward from the position shown in Fig. 9 to the position shown inFigs. 10 and 11. In moving downward the tool engages the fibers in thecorresponding notch 92 and forces them downward through the slot I04 inthe guard extension I02. Movement of the tool causes the fibers to belooped or folded and the tool inserts the looped or folded fibers intothe corresponding ferrule A as shown. Preferably the extension I02 isgrooved as indicated at I I5 to facilitate thefolding of the fibers. Assoon as the fibers have been inserted into the ferrule to form a tuft,the tool I I4 is moved upward and remains in its upper position untilafter the next intermittent movement of the ferrule supporting units.

Ferrule supporting units Figs. 6, '7, 12, 13 and 14 show in detail oneof the ferrule supporting units 20. Each unit comprises a body II6 towhich is secured an inner plate II8, the plate II8 being directlyconnected with one of the links of the chain 22. Secured to the outerface of the body I I6 and near opposite ends thereof are plates I20 andI22. As shown in Fig. 6, the body H6 is formed at its sides with twolongitudinal notches which 00- operate with the inner plate II8 to form.two longitudinal grooves. Longitudinal guide rails I24 and I26 on thebase I6 enter these grooves and serve to guide the unit 20 forlongitudinal movement.

The inner edges of the plates I20 and I22 are parallel and ferruleengaging jaws I28 and I30 are positioned between them. The jaws I28 andI30 are provided with registering notches which cooperate to provide thebefore-mentioned ferrule receiving recess. The jaw I28 is rigidlyconnected to the base I6 and the inner face of the notch therein ispreferably provided with a projection I32 which is shown more clearlyinFig. 9. The projection I32 may be formed as a separate piece inserted inthe jaw I28. The jaw I30 is longitudinally movable, being guided forsuch movement in undercut grooves in the opposite plates I20 and I22.Springs I34, I34 positioned in holes in the movable jaw I30 tend to holdthe said jaw in the position shown in Fig. 12 wherein it is separatedfrom the jaw I28. The left end face of the movable jaw I30 is inclinedand this inclined face engages acorresponding inclined face on atransversely movable cam slide I36. This slide is guided in undercutgrooves in the plates I20 and I22 and in an additional plate I38.

The plate I22 has an upward projecting boss I40 which serves a purposeto be presently described. The plate I22 also has in its front edge anotch I42 having oppositely inclined. edges. The purpose of the notchI42 will be presently described. Preferably, each unit 20 has a notch atits leading end in which is positioned a sheet metal clip I43. This clipis adapted to project into a corresponding notch in the next adjacentunit. The purpose of the clip I43 will be hereinafter explained. 1 1

During the insertion of the fibers B into the ferrule A, as shown inFigs. 7 and 11, the movable jaw I30 is separated from the jaw I28asshown Located beneaththe trimmingimechanis'm is a gathering mechanismwhich is'shown. in Figs. 17 to l9." The gathering mechanism comprisestwo jaws 200 and 202 which are in' thepositions shown by dotted'lines"in Fi'gfl'l during each intermittent movement of the ferrule carryingunits and which 'are moved tothe positions shown by full lines in thesaid figure immediately prior to the engagement of the-'fibers' by thecutting knives. The jaws 200 and 202 are shaped insection asshown inFig. 16 andthey have oppositely disposed notches. When the jaws aremoved toth'e positions shown in Fig. 16 and shown by full'lin'es in Fig.1'7 theyoverla'p each other at positions adjacent thenotchesso that theygather the fibers into a compact bunch preparatory to trimming.

Referring particularly'to Figs. 17 and 18, 204 is a bracket rigidlysecured to the base I6 by bolts 205. The bracket 204 carries a slide 206which is longitudinally movable along the bracket 204, being" guidedbyscrews 208 in slots 209. A tension spring 2I0 tends tomove the slide206'toward the right. The jaws 200 and 202 are connected with the'slide206 by means of vertical pivot pins 2 and 2I-2J: Longitudinally movablein the bracket 204 is a rack 2I4 and a pinion 2I6 connected with the jaw202 meshes with the rack. The pinion'ZIB is wider than the rack 2 I4 andprojects above it. A relatively thin pinion 2I8 connected with the jaw200 meshes with the upper portion of the pinion -2I6, but does not mesh"with the rack 2I4'. It will be seen that when the rack H4 is movedtoward the right, the pinion 2I6 is rotatedfin the counterclockwisedirection, thus moving the jaw 202 to its open position. As the pinion2I6 is rotated in the counterclockwise direction, the meshing pinion 2I8is rotated in the clockwise direction, thus moving'the jaw 200 toitsopen position. When the rack 2I4 is moved toward the left, the motionsare opposite and the Jews are moved to their closed positions. A tensioncoil spring'220 is] connected with the rack2l4 and tends to moveittoward the right and this tends to move-the jaws' to their openpositions.

Carried by the rack 2I4 by meansofa pinion 22I at the left'end thereofis an arm 222 which is pivoted for movement about the longitudinal axisofthe'pin; A spring 224 tends to move the arm 222 in thecounterclockwise direction, as viewed in Fig. 19. The rear; or inner endofthe arm 222- is provided with a depending'finger 226 which is in thepath of movement of the forward projecting end of the slide I36 of thecorresponding ferrule supporting unit 20. As each unit-moves toward thetrimming station the corresponding slide I36 engages the finger 226 tomove the arm 222 and the rack 2I4 toward the left, thus moving the jaws-200 and 202 to their closed fiber engaging positions, as shown in Figs.'16 and 17. The slides "I36 therefore serve not only for the purposebefore described, but also serve as parts of the actuating means forthegathering'jawsl j;

The parts are so positionedthat the 'jaw's'engage the fibers Bbeforethey are engaged by the trimming knives. As soonias the jawshave'en- 6: the] base;- 204 isfs 10 vertical plate 228. Pivoted to theplate 228 is an arm 230, shown in" Figs. 15,17 and 18, which isbiasedformovement in theclockwise directionby a' spring 232. A tail portion 234of the arm 230 extends toward the left and overlies the forward endportion'of the arm 222, as shown in Fig. 15. ,'The before-mentioned camdrum I08 is provided with a pin 236 which is adapted to engage'the rightend of the arm-230.: .When the pin engages the arm 230, the said arm "isrocked in the counterclockwise direction; the tail portion 234 thereofthus forcing the forward end of the arm 222 downward. As the forward endof the arm 222 moves downward, the rear. end thereof carrying the finger226 *movcsaupward,

the finger thus being disengaged' from the forward end portion'of theslide I36. This disengagement permits the arm 222 and the rack -2I4 tobe moved toward the right by the spring: 220, thus moving the jaws 200and 202 to theiropen positions as shown by dotted lines in Fig.3 1'].The pin 236 is so positioned on the drum that the openingof the jaws 200and 202 is'effected immediately after the completion of trimming so asto permit the trimmed brush to be moved toward the left. As the rack.2I4 moves toward the right it permits the slide 206 to be moved towardtheright by the spring 2I0. Thus the jaws are bodily moved'toward theright and are positionedfor engagement with the fibers carried bythenext following unit 20. v

Ferrule feeding mechanism into the recesses in the ferrule supportingunits when. the said units are at 'a station nearithe right end of themachine. If desired the. ferrule feeding mechanismicould be omitted andthe ferrules could be fedmanually;

The ferrule feeding mechanism as shown comprises a hopper 238 carried bybrackets 240, 240 on the base I6. Rotatablymounted in bearings in thesaid brackets 240, 240 is a transverseshaft 242. Secured to the shaft242 at the rear. end thereof is a belt pulley 244 which is engaged by abelt 246 passing over a pulley 248; The belt pulley 248 is carried by ashaft projecting from a speed reducing gearing generally indicated at250 and connected with a motor 252. The motor and the power transmittingparts connected therewith serve to rotate the shaft 242 in thecounterclockwise direction.

Carried by the shaft 242 is a disc 254 having a plurality of arms 256,256 projecting radially therefrom. The left wall of the hopper 238 isslotted to receive thedisc 254 and the arms 256. Each of the arms 256carries a prong 258 which extends in the direction of-rotation. I

A guide 260 is provided having its upper portion arcuate to conforintothe pathof movement of the prongs258 at the ends of thearms 256. "Theprongs travel 'within the guide and the guide carries flangesf262 whichextendinpositionedas to permitthe prongs"-2581topass by it withoutinterference;
